c++ - Where is exactly the definition of function-like macros such as CHECK & CHECK_EQ in Caffe? -

as noticed, there lots of function-like macros such check, check_eq, ... used in caffe headers , source files, example in blob.cpp have:

template <typename dtype> void blob<dtype>::fromproto(const blobproto& proto, bool reshape) { if (reshape) {   vector<int> shape;   if (proto.has_num() || proto.has_channels() ||       proto.has_height() || proto.has_width()) {     // using deprecated 4d blob dimensions --     // shape (num, channels, height, width).     shape.resize(4);     shape[0] = proto.num();     shape[1] = proto.channels();     shape[2] = proto.height();     shape[3] = proto.width();   } else {     shape.resize(proto.shape().dim_size());     (int = 0; < proto.shape().dim_size(); ++i) {       shape[i] = proto.shape().dim(i);     }   }   reshape(shape); } else {   check(shapeequals(proto)) << "shape mismatch (reshape not set)"; } // copy data dtype* data_vec = mutable_cpu_data(); if (proto.double_data_size() > 0) {   check_eq(count_, proto.double_data_size());   (int = 0; < count_; ++i) {     data_vec[i] = proto.double_data(i);   } } else {   check_eq(count_, proto.data_size());   (int = 0; < count_; ++i) {     data_vec[i] = proto.data(i);   } } if (proto.double_diff_size() > 0) {   check_eq(count_, proto.double_diff_size());   dtype* diff_vec = mutable_cpu_diff();   (int = 0; < count_; ++i) {     diff_vec[i] = proto.double_diff(i);   } } else if (proto.diff_size() > 0) {   check_eq(count_, proto.diff_size());   dtype* diff_vec = mutable_cpu_diff();   (int = 0; < count_; ++i) {     diff_vec[i] = proto.diff(i);   }  } 

where definition of these macros?

these macros part of google's glog logging library caffe using.
